A web developer from Brooklyn, New York, called Mark Suppes has successfully built a nuclear fusion reactor at home. If that’s not extreme DIY, I don’t know what is !!

He is part of a growing community of ‘fusioneers’, who are amateur science geeks who are building such reactors for fun, and with an eye to helping solve the world’s energy crisis. Mark Suppes, 32, is the 38th independent amateur physicist in the world to achieve nuclear fusion from a homemade reactor.

In nuclear fusion, atoms are forcibly joined, releasing energy. According to scientists, it is the ‘holy grail’ of energy production as it is completely clean and cheap. The mission is to find a way of making fusion reactors produce more energy than they need to run.
